MFC r228326-228327,228331-228332:
r228326:
  Controller does not require TX start command for every frame.  So
  send a single TX command after setting up all TX frames.  This
  removes unnecessary register accesses and bus_dmamap_sync(9) calls.
  et(4) uses TX interrupt moderation so it's possible to have TX
  buffers that were already transmitted but waiting for TX completion
  interrupt.  If the number of available TX descriptor is less then
  1/3 of total TX descriptor, try reclaiming first to get enough free
  TX descriptors before setting up TX descriptors.
  After r228325, et_txeof() no longer tries to send frames after
  reclaiming TX buffers.  That change was made to give more chance
  to transmit frames in main interrupt handler since we can still
  send frames in interrupt handler with RX interrupt.  So right
  before exiting interrupt hander, after enabling interrupt, try to
  send more frames.  This gives slightly better performance numbers.

  While I'm here reduce number of spare TX descriptors from 8 to 4.
  Controller does not require reserved TX descriptors, it was just to
  reduce TX overhead.  After r228325, driver has much lower TX
  overhead so it does not make sense to reserve 8 TX descriptors.

r228327:
  Remove et_enable_intrs(), et_disable_intrs() functions and
  manipulation of interrupt register access is done through
  CSR_WRITE_4 macro.  Also add disabling interrupt into et_reset()
  because we want interrupt disabled state after controller reset.
  While I'm here slightly change interrupt handler to be more
  readable one.

r228331:
  Rework link state tracking and TX/RX MAC configuration.
   o Do not report link status if driver is not running.
   o TX/RX MAC configuration should be done with resolved speed,
     duplex and flow control after establishing a link so it can't
     be done in driver initialization routine.
     Move the configuration to miibus_statchg callback which will be
     called whenever any link state change is detected.
     At this moment, flow-control is not enabled yet mainly because
     I was not able to set correct flow control parameters to
     generate TX pause frames.
   o Now TX/RX MAC is enabled only when a valid link is detected.
     Rearragnge hardware initialization routine a bit to leave
     enabling MAC to miibus_statchg callback.  In order to that,
     TX/RX DMA engine is enabled in et_init_locked().
   o Introduce ET_FLAG_LINK flag to track current link state.
   o Introduce ET_FLAG_FASTETHER flag to mark whether controller is
     fast ethernet.  This flag is checked in miibus_statchg callback
     to know whether PHY established a valid link.
   o In et_stop(), TX/RX MAC is explicitly disabled instead of
     relying on et_reset().  And move et_reset() from et_stop() to
     controller initialization.  Controler reset is not required here
     and it would also clear critial registers(i.e station address,
     RX filter configuration, WOL etc) that are required to make WOL
     work.
   o Switching to current media is done in et_init_locked() after
     setting IFF_DRV_RUNNING flag.  This should ensure reliable
     auto-negotiation/manual link establishment.
   o In et_start_locked(), check whether driver got a valid link
     before trying to send frames.
   o Remove checking a link in et_tick() as this is done by
     miibus_statchg callback.

r228332:
  Implement hardware MAC statistics counter.  Counters could be
  queried with dev.et.%d.stats sysctl node where %d is an instance of
  device.

Post r223774, the NFSv4 client no longer has multiple instances
of the same lock_owner4 string. As such, the handling of cleanup
of lock_owners could be simplified. This simplification permitted
the client to do a ReleaseLockOwner operation when the process that
the lock_owner4 string represents, has exited. This permits the
server to release any storage related to the lock_owner4 string
before the associated open is closed. Without this change, it
is possible to exhaust a server's storage when a long running
process opens a file and then many child processes do locking
on the file, because the open doesn't get closed. A similar patch
was applied to the Linux NFSv4 client recently so that it wouldn't
exhaust a server's storage.

MFC r226550 (pjd):

loop when data reconstruction was needed.

MFC r226551 (pjd):

MFC r226552 (pjd):
Never pass NULL block pointer when reading. This is neither expected nor
handled by lower layers like vdev_raidz, which uses bp for checksum
verification. This bug could lead to NULL pointer reference and resets
during boot.

MFC r226553 (pjd):
Always pass data size for checksum verification function, as using
physical block size declared in bp may not always be what we want.
For example in case of gang block header physical block size declared
in bp is much larger than SPA_GANGBLOCKSIZE (512 bytes) and checksum
calculation failed. This bug could lead to accessing unallocated
memory and resets/failures during boot.

MFC r226568 (pjd) [1]:
- Correctly read gang header from raidz.
- Decompress assembled gang block data if compressed.
- Verify checksum of a gang header.
- Verify checksum of assembled gang block data.
- Verify checksum of uber block.

MFC r225608 (avg, tools/ part):
zfstest: rename to zfsboottest and move to tools

MFC r225609 (avg):
zfsboottest: some additional enhancements

- redirect diagnostics printfs in the boot code to stderr
- do not read trailing garbage from a trailing block of a file

Also add my copyright to the file after making so many changes.

MFC r226611 (pjd):
- Allow to specify multiple files to check, eg.

	zfsboottest gpt/system0 gpt/system1 - /boot/kernel/kernel /boot/zfsloader

- Instead of printing file's content calculate MD5 hash of the file,
  so it can be easly compared to the hash calculated via file system.
- Some other minor improvements.

MFC r226612 (pjd):
Because ZFS boot code was very fragile in the past and real PITA to debug,
introduce zfsboottest.sh script that will verify if it will be possible to boot
from the given pool.

	# zfsboottest.sh system

Where "system" is pool name of the pool we want to boot from.

What is being verified by the script:
- Does the pool exist?
- Does it have bootfs property configured?
- Is mountpoint property of the boot dataset set to 'legacy'?

Dataset configured in bootfs property has to be mounted to perform more
checks:
- Does the /boot directory in boot dataset exist?
- Is this dataset configured as root file system in /etc/fstab or set
  in vfs.root.mountfrom variable in /boot/loader.conf?

By using zfsboottest tool the script will read all the files in /boot
directory using ZFS boot code and calculate their checksums.
Then, it will walk /boot directory using find(1) though regular file sytem
and also read all the files in /boot directory and calculate their checksums.
If any of the files cannot be looked up, read or checksum is invalid it will
be reported and booting off of this pool is probably not possible.

Some additional checks may be interesting as well. For example if the disks
contain proper pmbr and gptzfsboot code or if all expected files in /boot/
are present.

When upgrading FreeBSD, one should snapshot datasets that contain operating
system, upgrade (install new world and kernel) and use zfsboottest.sh to verify
if it will be possible to boot from new configuration. If all is good one
should upgrade boot blocks, by eg.:

	# gpart -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1

If something is wrong, one should rollback datasets and report the problems.

Fix the ar724x shift calculation when writing to the PCI config space.

This was preventing the ath driver from being loaded at runtime.
It worked fine when compiled statically into the kernel but not when
kldload'ed after the system booted.

The root cause was that PCIR_INTLINE (register 60) was being
overwritten by zeros when register 62 was being written to.
A subsequent read of this register would return 0, and thus
the rest of the PCI glue assumed an IRQ resource had already
been allocated.  This caused the device to fail to attach at
runtime as the device itself didn't contain any IRQ resources.

TODO: go back over the ar71xx and ar724x PCI config read/write
code and ensure it's correct.

    only keep track of the number of updates on tcp connections. state sync on
    all the other protocols is simply pushing the timeouts along which has a

    to a second to send it over.

    keep track of updates on tcp still though, their windows need constant
    attention.

This is just a build workaround. If you're actively using wireless,
you must still define AH_SUPPORT_AR5416 as I'm not sure what else
will break!

The real solution is to make the module build depend if AH_SUPPORT_AR5416
is defined, as well as make the 11n code in if_ath_tx.c and if_ath_tx_ht.c
completely optional (maybe depend upon ATH_SUPPORT_11N.)

This patch adds a sysctl to the NFSv4 server which optionally disables the
check for a UTF-8 compliant file name. Enabling this sysctl results in
an NFSv4 server that is non-RFC3530 compliant, therefore it is not enabled
by default. However, enabling this sysctl results in NFSv3 compatible
behaviour and fixes the problem reported by "dan at sunsaturn.com"
to freebsd-current@ on Nov. 14, 2011 under the subject "NFSV4 readlink_stat".

Make these two files conditionally build on UFS_ACL, as it doesn't
seem to be used elsewhere.

Since UFS_ACL is enabled by default for GENERIC kernels, this shouldn't
break anything - but please beat me to fix things if it does.

This reduces the footprint of the kernel on small embedded systems
(think <1MB flash for the compressed kernel image) just enough to
actually fit.

opt_inet6.h was missing from some files in the new NFS subsystem.
The effect of this was, for clients mounted via inet6 addresses,
that the DRC cache would never have a hit in the server. It also
broke NFSv4 callbacks when an inet6 address was the only one available
in the client. This patch fixes the above, plus deletes opt_inet6.h
from a couple of files it is not needed for.

Correct an error of omission in the implementation of the truncation
operation on POSIX shared memory objects and tmpfs.  Previously, neither of
these modules correctly handled the case in which the new size of the object
or file was not a multiple of the page size.  Specifically, they did not
handle partial page truncation of data stored on swap.  As a result, stale
data might later be returned to an application.

Interestingly, a data inconsistency was less likely to occur under tmpfs
than POSIX shared memory objects.  The reason being that a different mistake
by the tmpfs truncation operation helped avoid a data inconsistency.  If the
data was still resident in memory in a PG_CACHED page, then the tmpfs
truncation operation would reactivate that page, zero the truncated portion,
and leave the page pinned in memory.  More precisely, the benevolent error
was that the truncation operation didn't add the reactivated page to any of
the paging queues, effectively pinning the page.  This page would remain
pinned until the file was destroyed or the page was read or written.  With
this change, the page is now added to the inactive queue.

Avoid LOR between vfs_busy() lock and covered vnode lock on quotaon().
The vfs_busy() is after covered vnode lock in the global lock order, but
since quotaon() does recursive VFS call to open quota file, we usually
end up locking covered vnode after mp is busied in sys_quotactl().

Change the interface of VFS_QUOTACTL(), requiring that mp was unbusied
by fs code, and do not try to pick up vfs_busy() reference in ufs quotaon,
esp. if vfs_busy cannot succeed due to unmount being performed.

Add aligned_alloc(3).

The C11 folks reinvented the wheel by introducing an aligned version of
malloc(3) called aligned_alloc(3), instead of posix_memalign(3). Instead
of returning the allocation by reference, it returns the address, just
like malloc(3).

o Fix panic on module unload, that happened due to mutex being
  destroyed prior to pfsync_uninit(). To do this, move all the
  initialization to the module_t method, instead of SYSINIT(9).
o Fix another panic after module unload, due to not clearing the
  m_addr_chg_pf_p pointer.
o Refuse to unload module, unless being unloaded forcibly.
o Revert the sub argument to MODULE_DECLARE, to the stable/8 value.

This change probably isn't correct from viewpoint of VIMAGE, but
the module wasn't VIMAGE-correct before the change, as well.

Bunch of fixes to pfsync(4) module load/unload:

o Make the pfsync.ko actually usable. Before this change loading it
  didn't register protosw, so was a nop. However, a module /boot/kernel
  did confused users.
o Rewrite the way we are joining multicast group:
  - Move multicast initialization/destruction to separate functions.
  - Don't allocate memory if we aren't going to join a multicast group.
  - Use modern API for joining/leaving multicast group.
  - Now the utterly wrong pfsync_ifdetach() isn't needed.
o Move module initialization from SYSINIT(9) to moduledata_t method.
o Refuse to unload module, unless asked forcibly.
o Improve a bit some FreeBSD porting code:
  - Use separate malloc type.
  - Simplify swi sheduling.

This change is probably wrong from VIMAGE viewpoint, however pfsync
wasn't VIMAGE-correct before this change, too.

In FreeBSD we determine presence of pfsync(4) at run-time, not
at compile time, so define NPFSYNC to 1 always. While here, remove
unused defines.

Backout of backout: we need SI_SUB_PROTO_DOMAIN for pfsync, since
it needs existing inetdomain on startup.
